N. PETERS, PHOTO-LITHOGRAPNER, WASHINGTON D C 'p'a'ratus for carbureti'ng'air and -rrnn STATE-s PATENT -J. BARKER, OF SPRINGFIELD, MASSACHUSETTS,

IMPROVEMENT IN, APPARATUS "FOR-CARBURETING AIR.

- Specification forming partof Letters Patent N0.-76,80, dated April 21, 1868.

ratus, a portion 'of one side of the carbureter'being removed to show the interior arrangement; and Fig. 2'is a plan view of said apparatus.

My invention'relates to an apparatus for carbureting air for illuminating purposes and consists 'inthe arrangement of a small waterwheel andfan-blower, with their connections, incombinationwith a carbureter, whereby a cheap, compact, and reliable apparatus is obtained for supplying the requisite current of air to the carbureter and to the burners and it. also consists in a certain application and arrangement of steam-pipes in the air-conduit, whereby the entering air is deprived of moisture to a certain" extent, and its temperature raised; and also in an arrangement of steam- "pipeswithin the carburetor, for'the purpose of heating the hydrocarbon oil which is placed inthe carbureter thoroughly and uniformly.

The carbureter shown is, in its general construction and operation, similar to that de scribed in Letters Patent No. 66,777, granted to O. N. Gilbert and myself, for improved apgas, 'on the loth day of July, A. D. 1867.

' In the drawings, A is the sheet-metal case of such carbureter, containing thediaphragms B B and partitions C G, &c., and H is the airpipe, through which the necessary current of air is forced into the oarbureter.

To obtain a constant supply of the carbureted product, and a steady light during the hours when the artificial light is required, it is necessary to maintain a steady current of air through the pipe H, and this is efl'ected in a small way, and in localities remote from Water-power, by a meter-wheel, moved by a spring or weight, or a gas-holder for storage, or other like device is used. But where a large amount of the carbureted product is required,

as in the case of manufactories, it is essential to obtain the requisite air-supply by some means more economical, reliable, and-powerful, which means my apparatus affords.

It is further necessary that thep'ower applied to maintaining the air-supply should be independent of 'any other 'machinery,and it cannot therefore be properly obtained from the water-wheels or steam-engines which are used'topropel a manufactory, as the illuminating product is generally as necessary after the stoppage of the main wheel or engine as before, but would, of course, stop when'the latter stopped, unless maintained by separate power. My apparatus is designed to obviate this difficulty, also, by the use of an independent water-wheel of the propercapacity,'which is made an integral part of the apparatus, and, with the blower and attachments, 'is set up at the same time with the carbureter.

The construction of my invention is as follows: The carbureter, as shown, is set in close proximity to the water-wheel, but inpractice will generally be placed outside of the building to be'lighted, and at some distance from the water-wheel, the air-pipe H being extend ed from .the fan-blower to the carbureter,

through a reasonablejdistance, without injuriously retarding the current of ,air,

A' small turbine wheel, ofwhich E isthe upper disk amid the shaft, revolves within the case D, which is provided withwater-bay P, and a step beneath for supporting the shaft of the wheel, and is to be set in the wheel-pit or any place convenientto the water supply.

Bearings in L L" support the counter-shaft 0, upon which are thepulley G and toothed pinion h, which latter engages with the jackgear I upon the main shaft.- The case F of the fan'blower is supported above the water-wheel by the braces RN, and

the pulley 6 upon the shaft 0 of the blower is turned by a belt running on the pulley Gr.

By adjusting the relative size of the pulleys G and e, and the supply of water, the requisite speed of the fan can be obtained. The air enters at the sides of the case F, around the fan-shaft, and is expelled through the eduction-pipe M, whence it enters the air-pipe H, which is extended as directly as possible from the blower to thegcarbureter. Any of rrrcn:

the revolvingblowers for forcing .air maybe successfully applied for the purpose described.

The watenwheel may be allowed to revolve when the pipe V, at which the carbureted product enters the service-pipe, is closed, as the blower, in such case, will soon cease to force air into the carbureter.

By the means described the entire business of producing the illuminating product is brought under the control of the person in charge of the carbureter, and can be managed without reference to any of the other machinery of a manufactory, thereby removing a great objection to the use of air charged with hydrocarbonvapor as an illuminating agent in such places.

Asfthe air to supply the blower will. ordinarily be taken from the wheel-pit or other damp locality, it will take up. less hydrocarbon vapor if it entersthe carbureter before it is deprived of its moisture. vantageous to raise the temperature of this air to a certain extent before it is brought in contact with the hydrocarbon.

V To effect these objects is one of the purposes of my invention, and I accomplish it by carryingthe steam-pipe a, which entersv the carbureter, through a portion of the airpipe H, of which a part of one side is removed to show the inclosed steam-pipe. To obtain the most useful results I prefer to introduce thesteam-pipe intothe air-pipe at a.

point as near the fan-blower as possible, and, in practice, generally insert it at a point near the building tobe lighted. I

As the air-pipe H will generally be. colder than the heated air within it, some of the moisture in the air will be condensed and de' posited upon the inside of the air-pipe, and I provide drips at proper points beneath the air-pipe to remove the moisture, and also a stuffing-box at the point where the steam-- pipe enters the air-pipe. to allow for its expansion and contraction- By this means I avoid the expense. ofpacking or protecting the steamrpipe in its' passage to the carburet, er, and also. raise the temperature of the airsupply, and dry it to a certain extent.

The course of the steam-pipe after it leaves the air-pipe and enters the carburetor will be seen in Fig. 1, the arrangement being such that it passes through the different compartmentsso as to radiate the heat from it uniformly and thoroughly. The pipe at the bot tom of the carbureter is so placed that it will be covered by the gasoline or other hydrocar- It is also ad-.

bon, and its heat will be withdrawn to such an extent that no live steam shallescape at the outlet or drip pipe a. Alarger portion of the steam-pipe may be submerged, if necessary,

by altering its position in the upper compartments.

I do not claim, broadly, the introduction of steam-pipes into a carbureter, as the .same is shown in the generator patented by William Thompson, April 30, 1867.

The steam-pipeshown in said Thompsons apparatus is placed entirely in the lower parts of the case, and covered by the liquid to be heated, while in my invention the steam-pipe is carried through all the compartments, and heats the air thoroughly and uniformly'in all parts of the carbureter, as well as the hydro carbon.

The same result of heating the air contained within the carbureter has been frequently obtained heretofore by heating the room in which the carbureter is placed, or setting the carbureter upon a. coil of steam-pipe; but I believe my described arrangement possesses important advantages in cheapness, simplicity, and. certainty of operation over the indirect methods of heating the contained air before described, and also, when steam is obtainable, over the method of heating by a circulating heated fluid, which is described in the aforesaid Letters Patent of G. H. Gilbert. and myself.

Having described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-- 1. The steam-pipe a, placed within the airconduit H of a carbureter, or within a sufficient portion of the length of such conduit for the purposes specified, substantially as set forth.

2. The arrangement, within the air-space of a carbureter, of the steam-pipe a, for the pur erator, the arrangement of independent water.

wheel, fan-blower, and airconduit H, the whole forming an apparatus for carbureting air, sub-.

stantially as described.
